rlhe present invention relates to machines for manufacturing lvbottle, can,4 'and like closures of the cap variety, including those termed crown corks. Theinvention y.pen tains more particularly to,` means for feed 'ing the sealingl disks of corkor similar'omaterial of the closures to the vassemblingVdevices of the machine.

The main .object of the invention is to provide a simple and veiiicient attachment for cap making machines, which automatically delivers the sealing disks l`from anlass to the assembling machine withoutvregard to the thickness, weight, andrnore or less curved shapes of the disks.

With these and otherobjects in view, which will 4more fully appear as the nature of the invention is' better understood, the same consists in the combination, arrangement, and construction of parts hereinafter ldescribed, pointed out in the `appended claims and illustrated inthe accompanying drawings, itbeing understood .thatmany lchanges ,may b'emadein"l the size ,and proportionof the severalparts 'deftailszof construction within the scope of the y ap- ,pended claims' without v departing fromthe spirit or Qacrificing lany of the ladvantalges of the invention.

One of themany possible embodiments lof the Iinvention is illustrated in'thewaccomnaming drawings, in, which Figure 1 .is 'a central vertical. .section taken through a vfeedino" attachment constructed ,in *accordance* with lthe lpresent invention; Fig, 2 is asectiontalen von line v2j-2 of Fig,- 1501.1 @larger Seele; Fig-f 3 isa. .Section tekenen line ot' Fig, 1also on la larger scale; Fig'. 4, is a section 'similar to,y Fig, 1, showing, `,on a larger. scalenthe topvpoition ,of the apparatus; andiFig. 5 vis amsection in taken on line 5&5 of Fig, 4.

lnthe drawings,` the numeral l0, indicates a portion ofthe frame of crown ,corkassembling machine,I havingI uponl its table portion llinounted an upwardly extending support l2, which carries a vhopper 13, that yis in the lcase illustrated in theadrawings ot` cylindrical` shape, its lower Aportion 11i being conicalfto cause the disks therein to move toward its longitudinal center line. ',lvhebottom 15 vof thi'shopper is made, of a separate piece, and is adapted, as will hereinafter appear, to be vibrated or,` os- 'cillateol The bottom is slightly concave ,and provided,preferablypin'its center line with a circular outletl, the diameter "of which islslightly larger tlianitliat of fan individual sealing disk. Upon thel underface of the bottom is formed a downwardly projecting tubular extension, 17,1]through which,` the disks are discharged from the hopper. yThis extension,y which constitutes the .outlet of the hoppenis seated eccentrically in a bushing# 18, the latterfheing. rotatably mounted in a step-bearing 19,"that is suitably attached to the support'hl. To reduce undue friction between the bushing and thebearing, there are formediraceways l."20 and 2l inthe said bushingfandnbearing,` respectively, and inthese racewaysfrun balls 22 in the' well-,known nnnztnner.` The bushing'may be rotated inany suitable manner from the main driving shaftjof I'the assembling machine, for instance there may be mounted. upon 'the bushing a'pulley 23,

.over which runsy a` beltQel, that'runs "also over ac pulley 25, the latter beinghmonnted `upon a rotating shaftI 26 of the' assembling machine.` Sheaves y27 guidethe ,movement `ofhsaid belt. VIn orderL to prevent theVbotto1n15I from rotating with the bL1shin`g,'there isy formedfufpon theA underface of ,said'ibottom a lug 28!, carrying an anti-friction roller V29, which is seated in a substantially radially extending recess 30 th'at is'formed 'in `an extension 31 ofthe sup 'ort 12. E Theftubular outlet 1 of thehopper botten is .in 'aline-reset. with thlelrel .nach

32 of a stationary, preferably, vertically extending tube 38, leading to the transporting means 34 of the machine, which con- Veys the sealing disks one after the other to the assemblingV mechanism. The tube 33 is held above the transporting mechanism by av standard' 35, and is provided in its Wall vwith longitudinal slots 36, permitting of the insertion of a vpointed instrument for the purpose of properly arranging the disks therein, should by accident some of the same `travel thereinedgewise. l

In order to preventthe Whole mass of sealing disks from resting upon the hopper bottom and from clogging the outlet thereof, there is held a substantial distance above said bottom, Within the hopper, an inverted vsubstantially funnel-shaped member 37.

VThe hopper bottom is provided with perforations 88,V having eacha diameter that is smaller than that of a sealing disk. As the hopper bottom is oscillated or vibrated, broken disksand foreign matter are sifted out from the mass. To 'prevent such broken parts and foreign matterV from falling upon the step-bearing, there is `formed upon the ytubular extension 17 a collar 39, covering the step-bearing. f

Through the funnel-shaped member 37 extends preferably centrally a spindle 40, the upper end of which is screw-threaded, the said threads meshing vwith those of a Wingnut Lll, Whichabuts against the upper face `ofthefunnel-shaped member 37. To the .spindle 40 is attached in any suitable manner a disk 42, disposed a substantial distance above Vthe circular outlet 16. To this disk are ixedly secured downwardly extend-V .ing pins 43, Vwhich are' disposedv around the outlet of the bottom, their lower ends` reaching into perforations 38V inthe said bottom. yThe position of the-disk 4:2 and the pins 43 thereon may be adjusted in relation to the bottom by turning the Wing-nut il in one orthe other direction, Y v /Near the` outlet of the tube 33 there i yformed in the same a slot Main alinement withwhich is heldfupon the standard 35 a shiftable stop 45, adapted to be projected vinto` the said tube. so as to prevent disks therein from falling onto the transporting means 34. This mechanism is made use of if the assembling device-gets out Yof order and it becomes necessary to stop the feeding of disks thereto. Y l

T he operation of thisdevice is as follows: A mass of sealing disks is placed indiscriminately Vinto the hopper and rotation imparted to the bushing 1S. Inasmuch as the ,tubular outlet of the hopper bottom is seated eccentrically in saidbushing and a rotation of the hopper bottom is prevented as above Ydescribed,zthe said bottom will be oscillated or vibrated, with the result that the disks thereon, in traversing the outlet of the both tom, are caused to pass into the tubular extension thereof. As this tubular extension oscillates or vibrates above the Haring mouth of the tube 33, the disks will be discharged into the said tube. The continuous oscillation or vibration of the tubular extension 17 of the hopper bottom causes a proper stacking of the disks therein. No matter in what position they arrive in the tubular eXtension, they will be brought, by the continuous vibrating motion, before they reach the flaring mouth of the tube 33, into substan tially horizontal position and into exactly horizontal position as they pass into the stationary tube 33. The thickness and more, or less curved shapes of the disks does not aect the proper operation of the device. The stationary pins 43 around the circular outlet 16 of the bottom form, together with the disk 4t2, a cage which has a two-fold purpose, to Wit: First, it agitates the mass of'disk's on the bottom of the hopper as the said bottom is being vibrated, and, second, it prevents a clogging of the outlet of the hopper, in that it permits only a limited number of disks from moving toward the said outlet at a time.

It is obvious that, While herein a specific means has been disclosed for vibrating or oscillating the hopper bottom, any other means could be provided without departing from the invention, which lies mainly in providing a stationary cage Within the hope per and around the outlet thereof for the purpose set forth.
